Exit Bans for Diversion Traffic Introduced in Bavaria's Rosenheim District

A novel approach to managing traffic congestion on major highways is taking shape in Bavaria, with the district of Rosenheim leading the way. Since August 15, 2025, certain local roads along the A8 and A93 motorways have been closed to through traffic on holidays and weekends, marking a shift in traffic management practices[1].

These exit bans, aimed at preventing drivers from bypassing highway congestion by taking detours through small communities, are a response to extreme traffic conditions that paralyzed the region in the spring, causing congestion up to 20 kilometers in radius[2]. The district administrator of Rosenheim, Otto Lederer (CSU), announced these measures during periods of congestion on the A8 motorway[2].

The Rosenheim District Office's approach is supported by federal infrastructure bodies and aims to reduce congestion spillover into local towns caused by drivers avoiding highway jams. The model for this measure is the adjacent Austrian federal state of Tyrol, where similar regulations have been in force for some time[1].

As the first of its kind to be introduced nationwide, these exit bans will be enforced from Friday to Sunday, as well as on public holidays[3]. Violations of the exit bans may result in fines[4]. The A8 motorway is the location of the exit bans, with closures affecting a total of ten exits on the A8 and A93 motorways[5]. Signs on the motorways and at the roads indicate the exit ban[5].

The ADAC South Bavaria assumes that the bans will have a signal effect for other regions, with many inquiries having been received from other affected districts, as reported by District Administrator Otto Lederer[6]. Discussions and evaluations are underway about applying similar policies elsewhere in Germany and potentially in Europe based on this model[1].

An evaluation is scheduled for late September 2025, involving Austrian representatives, to assess the effectiveness and potential extension of these measures[1]. If successful, the Rosenheim experience could act as a test case influencing future traffic management practices both within Germany and in neighboring countries.

It's worth noting that exit bans for diversion traffic are recently introduced and location-specific within Bavaria[1]. While there is no publicly available evidence suggesting that such exit bans are commonly used across Europe’s major highways, the Rosenheim example could serve as a precedent for wider adoption.

In addition, diversion bans for trucks in the region are already in place when it is congested on the Inntal motorway due to Austria ordering metering traffic[7]. The police will monitor compliance with the exit bans, ensuring that drivers adhere to the new regulations.
